* | VC1: Fix intensity compensation performance regressionMason Carter2013-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix https://trac.ffmpeg.org/ticket/3204 The problem was that intensity compensation was always used once it was encountered. This is because v->next_use_ic was never set back to zero. To fix this, when resetting v->next_luty/uv, also reset v->next_use_ic. This improved (restored) performance by 85% when decoding http://bit.ly/bbbwmv Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | The field still remains in MpegEncContext because it is used by the mpeg4 decoder.

| | | | | | | | | | | | | | | | | | | | | | Use the intensity-compensated reference frame for subsequent fields/B-frames. Since we currently don't change the reference frame we have to maintain lookup tables for intensity compensation in the following dependent frames. Signed-off-by: Martin Storsjö <martin@martin.st>
